Fuel Temp Sensor on AN volt 4 ?

Recommended Posts

I've just started wiring up a G4 Storm to a mazda rx7 FD3S. Reading through all the documentation the 2 main temp inputs are for the water and air temp, which I sorted with the sensors in the manual.

I'd like to have the fuel temp as a correction too and was looking at using the AN-volt 4 input, but the manual says the difference between the temp and the an-volt is the temperature channels have an internal pull-up resister.

Can somebody recommend the sensor and pull-up resister I can use to get this to work correctly.

I'm looking at just using a wideband to free up the AN-volt 4 for use (manual shows wide and narrow band on ANvolt 3 & 4)

Any normal NTC temp sensor will do such as those you would use for coolant or oil temp.  If wired to an AN input use a 1kohm pullup as per page 39/40 of the manual.

Parts have turned up, I'm in the process of pulling the wiring through to the bulkhead and come back to the manual on pg39/40. The sensor I have is the bosch 0280130026 and it has 2 pins, is the diagram to one of the pins and the other to the sensor ground ? Shaun
